Teach calculating with roots and powers through a complete, classroom-ready Year 7 Core maths PowerPoint lesson aligned to Sparx code M135.

This is a genuine standalone lesson rather than a collection of disconnected worksheets. It develops pupils from prerequisite retrieval through explicit vocabulary, representation, matched teacher modelling, guided practice, responsive assessment and independent application.

Included:
• six-question retrieval starter with answers;
• precise vocabulary for base, exponent, power, square, cube, square root, cube root and inverse operations;
• three matched I Do–We Do examples with modelling canvases and worked solutions;
• exactly 12 mini-whiteboard questions, each followed immediately by its answer;
• 24 minimally different questions arranged in deliberate column order;
• Developing, Secure, Greater Depth and Super Challenge practice on one classroom-display slide;
• consolidated tier answers and a complete Super Challenge proof;
• misconception diagnosis and corrections;
• problem solving, constrained reasoning and exam-style questions;
• exit check and complete answers.

Questions have been checked for mathematical accuracy, precise wording, appropriate Year 7 demand and direct relevance to powers and roots. Greater Depth requires structural comparison, inverse reasoning, systematic enumeration and justification—not simply larger numbers. All essential pupil-facing text is at least 24 pt, with larger fonts used wherever space permits.

Ideal for whole-class teaching, cover lessons, non-specialist delivery, revision or departmental curriculum provision. The PowerPoint is editable, print-free and supplied with answers.
